After years of continuous development and innovation, Eyan has reached another important milestone in the international market. Its featured product, the CVH-500D 3A CNC Circular Knife / Slitter Knife Sharpener, has received strong recognition from a Korean customer and has officially entered the Korean market through a newly signed local agency partnership.
This cooperation is not only about equipment sales. It also represents international recognition of Eyan’s grinding technology, machine stability, and ability to evaluate different customer requirements through technical communication and sample testing.
A New Milestone in Korea
Before finalizing the partnership, Eyan worked closely with the Korean customer through multiple technical discussions and sample tests. Based on the customer’s actual tools and grinding requirements, Eyan reviewed key processing conditions such as tool size, grinding angle, and application needs to confirm whether the machine could meet the customer’s expectations.
Through this process, the CVH-500D 3A successfully gained the customer’s trust and became the key product for Eyan’s entry into the Korean market.
To support local promotion, the Korean customer will also introduce Eyan through Naver Blog, one of Korea’s most influential online platforms, as well as WordPress. In addition, Eyan’s product and cooperation news have been featured in the Korean customer’s company newspaper and blog, helping more Korean companies learn about the Eyan brand and the grinding capabilities of the CVH-500D 3A.
With support from a local agent and multiple promotional channels, Eyan will be able to communicate more closely with Korean customers and provide timely product information, technical support, and after-sales service.
About the CVH-500D 3A CNC Circular Knife / Slitter Knives Sharpener
The CVH-500D 3A is a CNC grinding machine designed for precision grinding of circular knives, slitter knives, and related industrial cutting tools. It is suitable for factories that require stable grinding accuracy, improved processing efficiency, and a better operating environment.
Main Specifications
- Grinding range: Ø65–Ø500 mm
- Grinding angle: +90°~-60°
- Grinding accuracy: ±0.005 mm
The machine features a fully enclosed sliding door design, which helps reduce grinding noise and creates a safer, more comfortable working environment. This makes it suitable for modern factories that value both machining quality and workplace conditions.
Possible Industries and Cutting Tool Applications
The CVH-500D 3A may be used in industries such as paper, plastics, film, rubber-plastic composites, cork, and cutting tool manufacturing. However, its actual application range is not limited to these industries.
Common types of tools that may be suitable for grinding include:
- Metal cutting blades
- Paper cutting knives
- Slitter knives
- Film cutting knives
- Plastic processing knives
- Other circular knives and industrial cutting tools
Because customer requirements vary widely, Eyan does not determine suitability only by industry category. Instead, the company usually evaluates the customer’s sample, tool size, material, cutting angle, and grinding requirements before confirming whether the tool is suitable for grinding and recommending the appropriate machine or technical solution.
In other words, whether a tool can be ground is usually confirmed after reviewing the actual sample provided by the customer.
Machine Features of the CVH-500D 3A
The CVH-500D 3A is designed not only for grinding precision, but also for efficiency, stability, and ease of operation in real production environments.
Key Features
- Standard grinding diameter up to Ø500 mm
- High grinding accuracy of ±0.005 mm
- Fully enclosed sliding doors to effectively reduce noise
- Advanced CNC system for stable grinding quality
- PLC control panel with automatic operation guidance
- Rough grinding and fine grinding can be completed in one process
- Ball screw and linear guide system for high-precision movement
- High-precision spindle design for both workpiece and grinding wheel accuracy
- Variable speed control for both the workpiece and grinding wheel
- AC servo drive system for stable operation
- Workpiece spindle head with NC rotary axis
- Optional rotary pneumatic cylinder for quick tool change
- Grinding motor options: 3HP or 5HP
Among these features, the optional rotary pneumatic cylinder helps shorten tool change time and reduce machine downtime. This is especially useful for customers who need frequent tool changes or want to improve overall production efficiency.
Continuing to Expand Globally with Grinding Technology
Starting from Taiwan, Eyan has expanded its products to overseas markets such as Japan, the United States, Thailand, and now Korea. The successful entry of the CVH-500D 3A into the Korean market further shows that Eyan’s technology and machine quality continue to gain recognition from international customers.
Looking ahead, Eyan will continue to focus on precision manufacturing, innovative development, and stable quality. By working closely with global partners, Eyan aims to help more customers from different industries solve their cutting tool grinding challenges and create greater production efficiency and industrial value.
Eyan wins the world with quality and moves forward internationally with technology.
